Hi,
I have two wallets set up using the firefox extension. I have downloaded the Yoroi app on android and have attempted to restore my wallet using 15 word phrase, however both wallet show up as empty and the account checksum does not match the one on the firefox extension. The second wallet I set up today in which I screenshotted the 15 word pass phrase and have written it down on paper. And while trying to add this to the mobile app, the account checksum again does not match.
